The aim of Classic, Quantum, and Post-Quantum Cryptography (CQPC) Workshop is to provide a forum for researchers to discuss current trends, methods, models and algorithms in classic, quantum, and post-quantum cryptography. In CQPC, we encourage the submission of papers in the field of Cryptography. Novel approaches and applications of these methods to real-world problems are welcome. Wholeheartedly all the researchers who work in all areas of CQPC to take part in the workshop and publish the research results.

There were 15 papers submitted for peer-review to this workshop. Out of these, 8 papers were accepted for this volume, 4 as regular papers and 4 as short papers.

Workshop is co-located with the International Conference “Problems of Infocommunications. Science and Technology” (IEEE PIC S&T′2023).
